The rain falls in torrents. It sounds especially evocative when it hits the metal ladder and stray pails at the rear of the house. Each point of metal evokes a different sound: bass sounds like violas, pitched cadence like lead violins, hollow sounds slightly enriched, like oboes, regular thumps like percussion. But the composition is open to the influence of wind and the physics of water dripping at different rates from the roof and its angles. And the music itself is not reproducible. It only happens once, now, it seems to say, so listen.
